This invention relates to an improved radio and television schedule, anobject being to provide a construction which is permanent in characterand which may be adjusted or changed to keep abreast of the times.

Another object of the invention is to provide a schedule to be used toindicate readily to a person the hour and the radio station to beconsidered on any day.

A further object, more specifically, is to provide a schedule to be usedin connection with a radio and to arrange the same as a separate articleof furniture or to apply the same to a clock or to the radio cabinet,and when in operative position to present means for indicating readilythe stations which have been previously selected for the daysinformation or enjoyment.

Another and more specific object is to provide a schedule structurecomprising a ring with slidable members associated therewith indicatingstations and with the dial or face of a clock for indicating time sothat a person may adjust the slides to any desired stations in themorning and then during the day may turn from station to 25 station atthe time specified.

Fig. 12 is a fragmentary view showing a modified form of the ring andassociated parts illustrated in Fig. 1.

Referring to the accompanying drawings by numerals, I indicates a clockof any desired kind having the usual face 2 and an hour hand 3. Theclock structure may be of the usual kind and the minute hand removed soas to present the showing in Fig. l. Surrounding the face 2 is a ring 4constructed as shown particularly in Figs. 4 and 11. This ring may bemade from wood, metal, bakelite or other material. As shown in Fig. 11,the ring has an inner solid section 5 and in the outer part numerousrectangu- Tar notches 6. The material I on each side of the respectivenotches is formed with V-shaped beads 8 so as to fit into the grooves 9and II] of the respective slide blocks I I as shown in Figs. 4 and 5.

It will be understood that there is a slide block II for each of thenotches 6 and on one side these blocks are left blank while on the otherside stations are indicated. These blocks are preferably held in placeby friction but may be readily pushed radially outwardly by pressingagainst the blocks and then moving the finger radially outwardly.

When using the device a person may secure a radio program from anewspaper and may decide which stations he desires to hear during theday or during a period of twelve hours. As soon as the selection hasbeen made he places block I in the ring 4 at the desired places. Forinstance, if a desired program is to be broadcast at one oclock fromWEAF, block II with this station is placed as shown in'Fig. 1. Otherblocks with other stations thereon are placed opposite differentgraduations on the clock face 2 so as to indicate the station and whenthe station is to broadcast. Having arranged the schedule for the day,nothing further is to be done as'far as the schedule isconcerned. Whenone o'clock arrives a person desiring to listen to WEAF merely turns tothis station on his radio. If the person desiring to hear station WEAFat one o'clock fails to remember this fact until after one, he willobserve that he has missed this broadcast when looking at the hand 3.Preferably all of the blocks II are turned over to show their blankfaces except the stations which have been selected.

It will be understood that the schedule does not in any way interfere oraifect the working of the clock or of the radio apparatus but merely isa sign to the person owning the schedule. This sign will indicate to theperson quickly the time selected stations come on the air. While theschedule is very desirable in connection with a clock as shown in Figs.1 and 2, it may be used in connection with other structures. Forinstance, it may be used directly on the front wall of a radio cabinet,as for instance cabinet l2 shown in Fig. 3. This cabinet and the radiostructure therein are old and form no part of the present inventionexcept in combination. As shown in Fig. 4, the ring 4 is secured to thecabinet by any suitable means, as for instance screws, adhesive or otherdesirable means. In Fig. 1 the ring is likewise secured in place byadhesive or other desirable means. As shown in Fig. 3 there areprovidedgraduations and numbers l3 indicating the outer part of the face of aclock dial. This ring is associated with ring while the usual pointer 14is of the usual construction and is adapted to be moved over the usualgraduation I5.

In Figs. 6, 7 and 8 a. modified structure is shown which is a separatepiece of furniture and which may be set on top of the radio cabinet,mantelpiece or other article of furniture in the room. In this form ofthe invention there is provided a basev l6 having a stand H on which adisk I8 is held by ascrew l9. Preferably the disk I8 is atanuappreciable angle so that the face thereof may be readily seen. On'the face of the disk I8 is arranged a clock face 2 and the outer part ofthe disk is provided with spaced radial slots 20 adapted to receive theblocks 2|, which blocks are H-shaped in cross section whereby they maybe readily slid into position as shown in Fig. '7. One face of theseblocks is left blank and the .oppositeface is provided with legendsindicating .a station. This structure maybe used in the same manner asthe structure shown in Fig. 1.

If desired, there could be provided as a second .modifiedform a disk 2|of celluloid or other materialiand on one face of; this disk indicationspresenting a clock face 2". On the outer part of the disk there areprovided, slots 22 and 23 through which thin blocks of celluloid orother material 2.4 are adapted to be moved so that when in operativeposition they will be as shown in Fig. 9. The disk shown in Fig. 9 maybe mounted ion a stand asshown in Fig. 4 or may be used in- .dependently thereof.

any of these forms function to secure the same results.

As shown in Fig. 1, an ordinary clock face 2 has been disclosed. Thehand 3 is an ordinary clock hand except for the'extension 3 whichpreferably projects slightly over the ring 4 so as to at right angles tothe face of the ring 4. Each of these slide plates is provided withnotches 25 and 2B. These notches accommodate the split pins 2'! whichare mounted in the ring 3. The parts are preferably so proportioned thatthe friction between the parts will hold the plates H in position. Inthe structure shown in Figs. 1 and 1a. a felt backing 28 may be providedand held in place by adhesive or other suitable means 3 whereby a.certain additional friction will be presented by the various blocks H.

I claim:

1. In a schedule of the character described, a

ring having a solid inner ring section and radial fingers with notchestherebetween, a slide plate arranged in each of said notches extendingfrom the front to the rear face thereof so as to be readily graspedbetween the fingers and the thumb when applying or removing, and meanson one face of each of said plates indicating a broadcasting station.

2. A radio schedule comprising a ring having a plurality of radiallyextending spaced fingers forming notches in the periphery, each of said.

fingers having a pair of guiding edges, a sliding block in each of saidnotches and letters on each of said blocks, said letters indicatingbroadcastingstations, said sliding blocks having grooves on their edgesfor receiving said guiding edges of said fingers, said blocks extendingentirely through said ring.

3. A perpetual radio and television schedule including a ring,aplurality of plates removably mounted on one face of said ring, each ofsaid plates having a'pair of notches, said plates being adapted to bepositioned so that adjacent notches will register and form asubstantially round aperture, and pins carried by said ring, saidpinsbeing positioned to extend through said apertures to holdsaid plates onsaid ring.

4. A radio schedule comprising a ring formed with a plurality of fingershaving substantially rectangular notches therebetween and'a pinreceiving notch in each side of each of said fingers, a plurality oflegend carrying plates removably mounted in said rectangular notches,said plates having notches coacting with the notches in said fingers,and pins adapted to be inserted into facing notches in the respectiveplates and fingers for holding the, plates removably mounted on thering.
